ISL91133IIQZ-T - Renesas Electronics

Description: The ISL91133 is an integrated boost switching regulator for battery powered applications. The device provides a power supply solution for products using a one cell Li-ion or Li-polymer battery. The device is capable of delivering up to 2.3A output current from VIN = 2.5V and VOUT = 3.3V. The no load quiescent current is only 108μA in Boost Mode and 45μA in Forced Bypass Mode, which significantly reduces the standby consumption.The ISL91133 offers a Bypass Mode operation where the output is directly connecte

ISL91133IIQZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the ISL91133IIQZ-T evaluation board user manual, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The selection of the inductor depends on the specific application requirements, such as output voltage, current, and ripple. Renesas provides a list of recommended inductors in the datasheet, and engineers can also use online inductor selection tools or consult with inductor manufacturers to find the best fit for their design.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and cooling conditions. As a general guideline, Renesas recommends keeping the ambient temperature below 85°C for optimal reliability and performance.
  • The ISL91133IIQZ-T has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The datasheet provides a detailed description of the overcurrent protection circuit and the calculation of the required resistor and capacitor values.
  • Renesas recommends using a high-quality, low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The specific capacitor type and value may vary depending on the input voltage and current requirements of the application.
